BLOCK BUILDING · AGES 6–12Block Builders
Rumble the Stone Golem carried the Heart Crystal into his Stone Vault! Wake the Glow Crystals, fix the Great Mine Lift and knock down his stone wall. A crystal mine adventure.
Every Block Builders party starts like this
The story, the call for help, the search for a hero and the launch. At your party the hero is your child: their everyday photo transforms into the hero on screen.
In this film the hero is Leo, an AI-generated boy. Sound on!
Why the world needs a hero
Beyond the hills, where everything is built one block at a time, lies Cubeland. Deep in the Crystal Mine glows the Heart Crystal, and every birthday it builds a brand new world for a young builder.
Rumble the Stone Golem stomps through the mine and carries the crystal down into his Stone Vault. He puts out the Glow Crystals in the deep tunnel and jams the Great Mine Lift.
Pip sounds the alarm, and it finds a hero at your party: the birthday child, who leads three crews of friends deep into the mine.

Three crews, one Commander
In every mission the red, blue and gold crews each play their own game, matched to their age. Every code they win flies to the big screen, and the birthday child, the Commander, plays the deciding game.
Wake the Glow Crystals
Rumble put out the Glow Crystals in the deep tunnel. Each crew's code wakes one, then the whole party shouts BUILDERS UNITE! and their light shows the way to his vault.
Fix the Great Mine Lift
The Great Mine Lift is jammed. Each crew brings back one gear, then everyone shouts POWER UP!
Knock Down the Stone Wall
A wall of rune stones blocks the vault. Each crew cracks one, the Commander chooses the way in, and the whole party shouts KNOCK IT DOWN!
Every guest goes home a hero
